| 摘要: |
| 在分析原-对偶内点法和连续性潮流方法计算系统输电能力各自优缺点的基础上．将两者结合，提出了一种系统输电能力的综合计算方法。该方法用原-对偶内点法优化得到的发电机出力值为连续性潮流方法提供最优的发电机出力方向。并用连续性潮流追踪系统从初始运行点到电压崩溃点的过程中各离散事件的变化过程，控制其向最优值靠近，从而提高系统的输电能力。对IEEE-14，30，118节点的算例做了测试，试验证明，该算法既能获得更大的输电能力，又能模拟系统实际运行状况，是常规的连续性潮流方法的完善。 |

| Abstract: |
| Based on the advantage and disadvantage analysis of the primal-dual interior point method and the continuation power flow method used for the computation of power system transfer capa-bility,an integrative computation method is proposed.The primal-dual interior point method is used to get the optimal generation dispatch direction.The continuation power flow method is used to trace the changing course of discrete events from the initial point to the breakdown point and con-trols them close to the optimal values to increase the transfer capability of power system.The re-sults of IEEE-14,30,118system test show that the proposed algorithm can not only attain larger power system transfer capability,but also simulate the actual operating process of a power system.It is an effective improvement of the general continuation power flow algorithm.This project is supported by National Natural Science Foundation of China(50177022),Teaching and Research Award Program for Outstanding Young Teachers in Higher Education Institutions of MOE,P.R.C.and Doctor Foundation of State Ministry of Education(1999005609). |
